REZUMAT

Sindromul LEOPARD este o afecţiune ce include multiple anomalii dismorfogenetice. Sindromul LEOPARD, ca şi sindromul Noonan, este determinat de mutaţii ale genei PTPN11. Autorii menţionează particularităţile diagnostice la 2 cazuri înrudite cu dismorfism facial. Cazul index este reprezentat de băiat de 10 ani evaluat pentru dis morfism cranio-facial asociat cu retard mental. Antecedente heredo-colaterale: fără consangvinitate; tatăl pa cientului şi soră cu dismorfism facial. Examenul clinic: retard staturo-ponderal, pistrui axilari, pete café- au-lait diseminate, dismorfism facial, pterigium coli, anomalii scheletice, retard mental. Investigaţiile sangvine şi eco-cardiografia: fără modificări. Pentru diagnosticul diferenţial s-au considerat sindroamele Noonan, Greig, neuro fibromatoza tip 1, sindromul Mc Cune-Albright. Evaluarea genetică: cariotip normal; secvenţierea genei PTPN11 a relevat mutaţia ce confirmă sindromul LEOPARD. Analiza genetică a relevat aceeaşi mutaţie la tatăl pa ci entului. Concluzii. Autorii au descris 2 cazuri familiale cu craniu dismorf, anomalii scheletice, pigmentaţia pielii, dizabilităţi mentale şi statură mică, justificând evaluarea genetică care a identificat o afecţiune genetică foarte rară.

ABSTRACT

LEOPARD syndrome is a complex disorder characterized by multiple dysmorphogenetic features. Both syndromes LEOPARD and Noonan are caused by different mutations in the same gene (PTPN11). Authors emphasize diagnosis peculiarities in two related cases with facial dysmorphism. Index case is represented by a 10 year-old boy admitted for evaluation because of cephalofacial dysmorphism associated with mental disabilities. Family history: non-consanguineous parents; the father’s case and his sister with face dysmorphism. Clinical exam: short stature, impaired nutritional status, axillary freckles, widespread café-au-lait spots, face dysmorphism, webbed neck, skeletal anomalies and mental retardation. Blood investigations and cardiac ultrasonography: no anomalies. Differential diagnosis includes Noonan syndrome, Greig syndrome, type 1 neurofibromatosis, Albright syndrome. Regarding patient genetic evaluation: normal karyotype; DNA sequencing revealed mutation in PTPN11 gene suggestive for LEOPARD syndrome. Authors also found same mutation for probant’s father. Conclusions. Authors described two cases with dysmorphic skull, skeletal anomalies, skin pigmentation, mental disabilities and short stature, justifying further genetic evaluation that revealed a very rare disorder.
